' Our invention relates to surgical treatment as applied to fractures- It has especial reference to cases of fracture of the hip or 1ong bones of the limbs which require a relatively long period of tension applied in the lineof the bone axis in order to hold the fractured ends in alignment after being set, and unt l they knit; such tension, for example, as is commonly given by a suspended weight.

The object of our invention is to provide a comfortable method of treatment by means of a simple and eflective' apparatus; and to this end it consists primarily in means for reciprocally stressing the fractured limb and its companion sound limb in such wise that the latter oifer's compression resistance to tension applied to the injured limb; and secondarily, in means anchored to both limbs, together with means for varying the relatlve positions of said anchoring means adapted to place the injured limb under axial tension.

In the accompanying drawings, we have shown our apparatus in its preferred form, though it is to be understood that changes in form and arrangement may be made therein without departing from the spirit of our invention as defined by the claims hereunto appended. j I

In the drawings, Fig. 1 is a plan view, partly broken, of our apparatus.

Fig. 2 is a side view, partly in section, taken on the line 22 of Fig. 1.

Fig. -3 is a plan view showing the applica-, tion of the apparatus to the limbs.

1 and 2 are bars or strips, which'form the anchors for the device. 3 is a member for carrying the adjusting mechanism. The anchor 1 is connected with one side of the memher 3, by the rods 4, which are preferably removably fitted to a lug 5 of said member.

Within the member 3 at the opposite sideis'a slide 6 mounted in grooves 7. To this slide are fitted, preferably removably, the rods-8, the ends of which carr the screw for convenient adjustment. The outer ends of the sleeves 9 are formediwith balls '10 for 1 universal movement in seating lugs. 11, secured to the anchor bar2. A tightening ferthreaded a screw 14 journaled in end platesv 15 of the member 3, andprovided with a handle 16, preferably removable.

17 in Fig. 2 indicates a scale on the face of the member 3, and 18 is an associated pointer carried by the slide 6, whereby the amount of angular adjustment may be observed.

Referring now to Fig. 3, 19 are the limbs of a patient. At 20 is indicated the cast on the injured leg covering and holding the reduced fracture against lateral displacement. Upon this limb below the knee is the cast 21 in which is incorporated one of the anchor bars of the apparatus; and upon the sound limb incorresponding position is the cast 22 in which the other anchor bar is incorporated. By operation of the screw 14, the relative position of the two sides of the apparatus is varied, resulting in reciprocal stress which will place the injured limb under such axial tension as may be determined upon. By means of the sleeves 9 and the ferrules 12, such adjustments may be made as will give comparative comfort to the patient while insuring roper fixation.

e c aim 1. An apparatus for reducing fractured positions of the two bars. to apply tensionmearly of the fractured bones, consisting of a carrying member a connection between said member and one of said bars; a slide carried by said member; means for movin the slide;

and a connectionbetwen said sli e and the other of said bars.

I An apparatus for reducing fractured limbs comprising a pair of anchor bars adapted for connection one with the injured and the other with the sound limb; and intermediate means for adjusting the relative positions of the two bars to apply tension linear- 1y of the fractured bones, consisting of a car:

rying member; a connection between said member and one of said bars; a slide carried by said member; a nut and screw for moving 1 the slide;' and a connection between said slide and the other of said bars.

4:. An apparatus for reducing fractured limbs comprising a pair of anchor bars adapted for connection one with the injured and the other with the sound limb; and intermediate means for adjusting the relative positions of the two bars to apply tension linearly of the fractured bones, consisting of a carrying member; a connection between said member and one of said bars; a slide carried by said member; means for moving the slide; and a connection between said slide and the other of said bars said last named connection having an adjustable universal joint. 5. An apparatus for reducing fractured limbs comprising a pair of anchor bars adapted for connection one with the injured and the other with the sound limb; and intermediate means for adjusting the relative positions of the two bars to apply tension linearly of the fractured bones, consisting of a carryin member; a connection between said mem r and one of said bars; a slide carried by said member; means for moving the slide; and a connection between said slide and the other of said bars, said last named connection having an adjustable universal 'oint comprising a screw sleeve with a ball earing and a setting ferrule associated with said bearing. 40 In testimony whereof we have signed our names to this s e'cification.
